5 oiai'msj- (cram-42 This invention relates to bottle closures and has shown in Figs. 1 and 4, where it will be seen that for its object to provide-a closure which is secured the top of the bottleis covered by the convento and becomes a part of the bottle and requires tional thread-on metal cap [5. This cap, when destruction before the contents can be removed. removed, exposes the closure member, as shown 5 When the closure is destroyed, that fact is plainly in Fig. 3. The closure member being secured to 5 indicated so that it is impossible for the bottle the top of the bottle neck by being fused or inteto be refilled without that fact being clearly grally united therewith after the bottle is filled, apparent. forms a positive non-leak closure for the bottle.

More particularly, the invention comprises a To secure access tothe contents 9 of the bottle,

The closed bottle is mouth, said member having an enlarged ball- 55 shaped lower end and having a break-off groove formed adjacent the ball-shaped lower end whereby downward manual pressure on the ballshaped lower end will cause it to break ofl on the line of said groove and fall into the bottle.

3. A bottle closure comprising, a conical frangible member fitting into the neck of a bottle, said member having a laterally extending flange at its upper end fused to the top of the bottle, and provided with an enlargement at its lower end, said member having an annular break-off groove located between the flange and enlargement, the portion of the member where said groove is located being of less diameter than the diameter of the enlargement, whereby said enlargement when broken off on the line of said groove will fall into and remain within the bottle.

4. A bottle closure comprising, a closure member fitting into the neck and closing the mouth of a bottle, said closure member being fused to the bottle neck to form an inseparable portion thereof, said member having an enlarged. inner end attached to the closure member by a neck portion of less diameter than said enlarged inner end, said enlarged end being adapted to be detached from the closure member and form by said detachment an opening of less diameter than the diameter of the enlarged end whereby said end when separated will fall into and cannot be removed from within the bottle.

5. A bottle closure comprising a closure member fitting into the neck of a bottle and fused thereto to form an integral part of the neck, said member having an attached inner end portion adapted to be separated from it in such a way as to cause said part to fall into the bottle,

said endrportion being connected to the closure member by a neck portion of less diameter than the closure member and the end portion whereby the separation of said end portion from the closure member forms an opening too small to permit the'passage through it of the separated end portion.
